SELF-OILING CARA-WHEEL- Specification of Letters Patent.

Patented Nov. 6, `1906.

Application filed December 19, 1905. Serial No. 292,415.

To all whom it may concern.-

Be it known that I, HENRY EGGEEs, a citizen of the United States of America,residing in the city and county of Denver and State of Colorado, havejinvented a new and useful Self-Oiling lCar-Wheel, of which the following is a specification. ,-A

My invention relates to improvements in self-oiling car-wheels; and the objects of my invention are, rst, to provide a car-wheel having a removable axle-oiling bushing; second, to provide a self-oiling car-wheel provided with a renewable axle-oiling bushing and an inclosed hood that is provided with a locking device to prevent its accidental disy placement from the car-wheel. l attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure lis a vertical sectional view of my improved self-oiling car-wheel, illustrating the manner in which the lubricant is fed to the axle-journal. Fig. 2 is a iront elevation of the car-wheel, the oil-cap being in section, so as not to obscure the locking-yoke and other parts. Fig. 3 is a perspective view of the locking-yoke, and Fig. 4 is a side elevation of the hub-bushing.

Similar iigures of reference refer to similar parts throughout the several views.

Referring to the drawings, the numeral 1 designates a car-wheel.

The hub 2 is bored out to receive a brass or other antifrictional metal bushing 2a, which preferably extends entirely through it from the front side to within a ver short distance from its rear end, in which I orm a counterfrom its front end to close to its rear end, and

from the bottoms of the apertures oil-holes 12 are drilled through itsy shell. A circular rownof oil-holes 13 are drilled through the yoke-washer, which allow oil to work freel into the oil-channels in the bushing.

The periphery of the hub is provided with a thread 14, and a cap 15 is threaded to it.

This cap is made large enough to leave an oil well or chamber 16 between the end of the hub and the outer wall of the cap. Alu 17 19 of the car-wheel.l In this hole lplace an' expansive coiled spring 20 and also apawl 21, which comprises a pin of two diameters, the smaller diameter of which projects loosely into the spring and the larger diameter of which extends and fits slidably into the hole 18 and bears against the end of the spring at the shoulder 22, formed at the junction with the smaller diameter of the pin. .The outer end of this pin-pawl is provided with a ratchet-engaging pawl-tooth 23, and on the adjacent s1de ofthe flange of the car-wheell form a projecting circular lug-surface which is provided with a number of ratchet-teeth 24, which are arranged in a circular row. The pin-pawl engages these teeth which are arranged on the car-wheel relative to the direction in which the cap screws onto the hub, so that the pawl will run over the teeth while the cap is being screwed onto it, the pawl being heldin resilient engagement with them' by its actuating-spring 20 and will engage a ratchet-tooth when the cap is fully screwed tightly onto the hub and will thus lock the cap against accidental displacement. The pawl can be moved back into its supporting-aperture bya pin or other suitable means, or a slot may be drilled into the lug that will permit a pin to be inserted against the front end of the spring to move it back enough to permit the pawl to be moved back out of engagementV with the ratchet-teeth. The cap is illed with grease or any suitable oil which Works into and along the recesses of the bushin and through the oil-holes to the journal o the axle.

Having described my invention, what I claim as new,and desire to secure by Letters Patent, is

1. The combination of a car-wheel having a hub, a grooved bushing therein, a cap threaded on the hub and la spring pressed pawl carried by the cap, there being ratchetyteeth on the wheel adapted to be engaged by the pawl.

2. The combination of a car-wheel, prol vided with an axially-bored hub, and a bushing therein with an axle rotativelymounted in said bushing, there being oil-passages in said bushing adaptedI tordistribute `Oil tcfthewsuroar-Wheel against accidental displacement, as face of said axle, an oil-reservoir cap threaded set forth. ro to said hub to inolose the end of said aXle and In testimony whereof I aIiX my signature hub, there being ratchet-teeth arranged in a I in presence of two Witnesses.
